Inbreeding leads to reduced biological fitness and genetic disorders
the verdict
SUPPORTED
the evidence backs this
confidence 83/100
Evidence consistently shows that inbreeding and increased homozygosity lead to a higher prevalence of genetic disorders, congenital anomalies, and reduced biological fitness due to the unmasking of deleterious recessive alleles.
